"I'm excited, because the second season is really digging into the characters even more," she said. "And they're definitely going to find out who the killer is. So I hope the viewers hang in there, so they can find out what's going on with this journey and adventure."

Allman admitted that she personally has no idea who the murderer is.

"No-one knows who the killer is - information is pretty much released script to script, you know?" she said. "I know as much as anyone else who's watching it, pretty much as the plot is going along.

"I have my speculations still. Honestly, I hope that I'm the killer. I know that's bad to say when you're thinking, 'If this really did happen' and that this really does happen to people, but just from an acting standpoint that could be really fun."
